Static Brakes - BTM

BTM are static brakes which use hydraulic pilot pressure for release. The braking action is obtained by a series of discs and springs acting onto the main piston.

The brake housing is of spheroidal cast iron and extrusion proof seals are suitable for high pressures. The brakes are to work with hydraulic mineral oil with vis- cosity ISO VG 150 (15°E at 50°C); Oil enters through the “Oil” port, the main piston opens the discs and unlocks the main shaft.

Pilot opening oil pressures are shown in the following table. Change oil after first 50-60 working hours and then every 500 - 1500 hours depending on working conditions. The BTM brakes cannot work without oil. Fill the lubrication oil through port “O” **. For vertical mounting specify the need of the optional elbow filling connector. The BTM brakes are for application on various types of hydraulic motors.
